Tube and Pipe Fabrication

The tube and pipe fabrication technology area covers sawing (band, circular, and friction) and other cutting processes, such as abrasive, flame, laser, oxyfuel, plasma, and waterjet. It also discusses forming processes, including bending and end forming. Finally, it includes a handful of miscellaneous processes, such as trimming, beveling, finning, grooving, threading, and spinning.

Push pointed tubes

Tube prep for the drawing step

August 12, 2008

By: ,

Pointing, sometimes called tagging or swaging, is a process that reduces a tube's end to permit it to pass through a draw die for a drawing operation. After the tube end goes through the draw die, gripper jaws converge on the point to begin the draw operation. Push pointing is accomplished by gripping a tube and advancing pointing dies over the end, resulting in a reduced end diameter.

CAD system CNC tube bending

From the CAD station to the production floor

July 15, 2008

By:

Conventional tube bending data, regardless of format, is entered manually and therefore susceptible to errors. A modern approach involves using a CAD system to generate a STEP file, which the CAD program exports directly to the bending machine. This method is fast and eliminates errors. The drawback is that such a system requires additional database management efforts.

Will your tube pass a dimensional inspection?

July 15, 2008

By:

Verifying that tube was bent correctly is not as simple as it sounds. Bending specifications and tolerances aren't cut-and-dried, but are open to interpretation. The fabricator, the end user, and the check fixture designer might have three different perspectives on specifications and tolerances. Achieving a consensus is critical for designing and manufacturing a check fixture.
